They are both novelty items, but if I had to ride one or the other it would be the bike. It reminds me of the "America" bike from Easy Rider which I think is a cool bike and I'm no HD guy.
I think this is a conflicted woman in a man's body who hasn't finished the 'conversion.' Seeing people like this, I hope they find happiness when they reach whatever point they are trying to occupy.
Now, the bike, the Boss Hoss V-8 (or similar construction) is like the Amphicar car/boat. Car and Driver said of that, "it handles like a boat on land and a car in the water."So there really is a similarity to the two primary objects in that pic. Neither is really what you would think of when trying to describe an archetype of"what is a woman" or "what is a motorcycle?"
As for remindingcaseyjones955 of the 'Captain America' bike, here are some pics from the H-D Museum when I was there a few years ago. Dennis ("Billy") Hopper's bike too, a more-practical ride.
Everytime I see the Captain America bike all i can think of is the interview i saw with Peter Fonda where he said the bike rode horrible, stiff and no seat cushion, but great movie and great piece of history.
